Zusammenfassung
Studienziel: Die Pathologien des Labrum acetabulare spielen eine verstärkte Rolle in der Behandlung
des belastungsabhängigen Hüft- bzw. Leistenschmerzes. In deren Therapie hat sich die
Hüftarthroskopie zunehmend als adäquates Verfahren bewährt. Bislang existieren allerdings
nur wenige Studien bei größeren Kollektiven mit validen Ergebnissen bezüglich der
Wertigkeit des Verfahrens in einem homogenen Patientengut. Methodik: Im Rahmen einer prospektiven Erfassung wurden alle Patienten seit 9/2002 bei denen
eine Hüft-Arthroskopie in unserer Klinik durchgeführt wurde nach klinischen und radiologischen
Aspekten evaluiert. Der Einschluss in die vorgestellte Studie erfolgte bei arthroskopischem
Nachweis einer Labrumläsion, sowie intraoperativem Ausschluss eines kartilaginären
Defektes (>I° in der Klassifikation nach Outerbridge) im Bereich des Hüftkopfes und/oder
des Acetabulums. Des Weiteren wurden nur Patienten ohne präoperativen radiologischem
Verdacht eines knöchernen femoroacetabulären Impingements oder einer Hüftdysplasie
in die Untersuchung aufgenommen. Das minimale Follow-up wurde auf 2 Jahre festgelegt.
Zur Erfassung von kombinierten Resultaten verwendeten wir verschiedene etablierte
Scores (VAS, modifizierter Harris-Hip-Score, Larson-Hip-Score). Ergebnisse: Anhand der dargestellten Kriterien wurden insgesamt 34 Patienten im o. g. Zeitraum
primär in die Studie aufgenommen. Hiervon konnten 31 Patienten (18 w, 13 m) im Alter
von 14 - 49 (29,9) Jahren vollständig persönlich klinisch (incl. VAS, LHS und MHHS)
als auch radiologisch nachuntersucht werden. Durchschnittlich 33,6 Monate (Range 25,2
- 47,8) postoperativ zeigte sich eine signifikante Verbesserung (p > 0,05) der subjektiven
Beschwerden (VAS: 6,0 vs. 2,7), sowie der angewandten kombinierten Scores (mod. Harris-Hip-Score:
63,1 P. vs. 85,9 P., Larson-Hip-Score: 57,8 P. vs. 79,6 P.). Schlussfolgerung: Die Arthroskopie des Hüftgelenkes stellt eine gute und sinnvolle Methode zur Verbesserung
von belastungsabhängigen Hüft- bzw. Leistenschmerzen bei Läsionen des Labrum acetabulare
ohne begleitende ossäre Pathologie (Dysplasie oder FAI) dar.
Abstract
Purpose: Arthroscopic treatment of labral pathologies in the hip has evolved considerably
in recent years. Even though it has become an accepted therapeutic method there are
only a few prospective outcome studies in extended patient collectives. Patients and Methods: Since 9/2002 all patients undergoing hip arthroscopy in our institution have been
prospectively evaluated by clinical and radiographic aspects and the use of several
questionnaires (modified Harris hip score [MHHS], Larson hip score [LHS], visual analogue
pain scale VAS]). In the present investigation only patients with an arthroscopically
proven torn labrum and the absent of cartilage defects >I° according to the Outerbridge
classification) with a minimum follow-up of at least 2 years postoperatively were
included. Furthermore, only individuals without radiological evidence of a femoro-acetabular
impingement or hip dysplasia were assessed. Results: According to the inclusion criteria 34 patients were initially enrolled in the investigation.
Out of them 31 individuals (18 female, 13 male) with a mean of 29.9 years (range 14
- 49) could be followed up clinically and radiologically. At an average of 33.6 months
(range 25.2 - 47.8) postoperatively we found a significant increase in the visual
analogue pain scale (VAS: 6.0 vs. 2.7). Furthermore there was a significant improvement
of the modified Harris hip score as well of the Larson hip score (MHHS: 63.1 P. vs.
85.9 P., LHS: 57.8 P. vs. 79.6 P.). Conclusion: Arthroscopy of the hip can provide a significant improvement of patient satisfaction
and hip function in patients with labral tears without associated cartilage or bony
pathologies (dysplasia, FAI).
